That PCmag review is hilarious
If you're serious about learning a language, you're much better off with Rosetta Stone$169.00 at Rosetta Stone, PCMag's Editors' Choice among paid language-learning programs, or Duolingo, the Editors' Choice among free programs.
Despite all that, they are not entirely wrong, you would probably be better served elsewhere
. It looks like the main advantage of Mango languages seems to be the amount of languages. Yes, it is probably a challenge to find beginner stuff for four Arabic variants, Dzongkha, Tagalog, Armenian, etc.
But it looks like a lot of money for not that much progress in the languages with more alternatives, it looks suspiciously colourful (yes, that sounds weird.
I looked at the info about Greek and French. The Modern Greek learners may be excited there is something (2 levels), but now there is Duolingo and Language Transfer and I even guess they could get you further. French: there are four levels, which looks nice at first but the last one is nowhere near the intermediate level. It is perhaps A2ish stuff. Perhaps. So, again there are lots of better alternatives, such as a normal coursebook with audio.
Also, I find it really weird, when a language program is so focused on being sold to libraries, schools, and similar institutions. These have one thing in common: the people who buy this stuff are usually not the people who use this stuff, and usually do not even understand what the user needs. The marketing clearly shows it. There is only one offer for individual learners and it is not even an attractive one, most services like this have several offers giving a bonus to long term subscribers.
You know, I've been looking around for stuff like this lately. My boyfriend will need to learn either French or German, when we are moving abroad in a year. He is not a bookish type, so it is gonna be a challenge. And I am a bit frustrated with most tools like this being just bad. As if it didn't suffice he'll need to use a non-native base. His English is quite good but still. At least he should be getting the most value for the increased efforts of learning French or German from English. And the market being flooded with stuff like this isn't helping.
